This is not so difficult to understand, because from common perspective the unparticle hypothesis would effectively mean, no distinct Higgs particle signal will be ever found, until we achieve collider jets, composed of unique particles to demonstrate it - because Higgs field interaction would have a character of kink widespread over ultraviolet part of mass-energy spectrum. Could prof. Higgs deserve Nobel price, if it turns out Higgs boson is just some Unhiggs?
In more illustrative way, Unhiggs field is analogous to coat of virtual quarks, in which all elementary particles are surrounded at small distances. This coat glues particles together at smallest distances. Such unstable particles can still be observed by their collective effects, for example by jet suppression during particle collisions. Just because it's difficult to call them particles they're called an unparticles. It's responsible for so called Yukawa coupling, responsible for pairing and gluing of nucleons and quarks inside of atom nuclei, for formation of top-quark pairs, glueballs, pentaquark and another artifacts, which were observed recently at Tevatron.
From Standard model follows, the product of Higgs boson Yukawa coupling to the left- and right-handed top quarks have nearly the same rest mass (173.1±1.3 GeV/c2) like those predicted for Higgs boson (178.0 ± 4.3 GeV/c2). It means, Higgs boson was observed already at Tevatron as a product of top-quark coupling and identified by dilepton channel of top-quark decay.
In AWT such field exists at all scales and it manifests by Casimir force mediated by virtual photons at micrometer scale, or dark matter at megaparsec scale, for example. It means, Higgs field has a scale invariant character of fuzzy unparticles, which are changing their size accordingly to carrier particles. The combination of trivial and topological band insulators within topological insulators and superconductors is bringing anyons and plektons - unparticles that behave neither according to purely Bose nor Fermi statistics.
The title of recent NewScientist article "In SUSY we trust: What the LHC is really looking for" illustrates clearly, physicists are aware of the conceptual problems of Higgs field concept. The article should be interpreted like: "Uhm, well, ... we really don't believe, Higgs boson will be ever found at LHC - so we should concentrate to supersymmetry, for not being blamed completely before publicity". The question is, whether physicists could admit openly before publicity, LHC is useless with respect to search of Higgs boson even by their own theories, if they wasted so much money in it.
This is a demo, how seemingly spontaneous scientific PR is basically working. Dual situation appeared recently in media, when scientists started to speculate, (primordial) gravitational waves cannot be found at all due the "quantum-spread", which renders detectors of gravitational waves useless. With respect to AdS/CFT duality the success or problems with particle search at Planck scale will be replicated/mirrored at cosmological scales (WIMPs detection) and vice-versa.
The similar U-turn we could expect later regarding estimations of LHC collider safety. The most problematic part of Unhiggs detection at LHC is the strangelet controversy: in contact with terresterial matter it could enable avalanche chain formation of clusters of particles, analogous to stable microscopic black holes predicted by Randall-Sundrum model. Recently A. Choptuik demonstrated, when extra-dimensions are involved, black hole could be formed with compare to existing CERN safety analysis, considering Hawking radiation as the only mechanism of black hole evaporation (1, 2, 3). In addittion, CERN considers, black hole could interact with its neighborhood via gravitational interaction only, thus purportedly neglecting their electromagnetic interaction, which is 10e+41 x stronger.
"Does that mean the LHC will make black holes? Not necessarily", Choptuik says. "The Planck energy is a quintillion times higher than the LHC's maximum. So the only way the LHC might make black holes is if, instead of being three dimensional, space actually has more dimensions that are curled into little loops too small to be detected except in a high-energy particle collision. Predicted by certain theories, those extra dimensions might effectively lower the Planck energy by a huge factor."
Well, if some extra-dimensions could wipe-out one quintillion factor (?!?) of LHC safety expected, can scientists admit, they're openly planning to verify theory, which predicts formation of stable black holes just by formation of black holes at LHC? Could CERN physicists ever admit, it could be qualified as an criminal act by the rest of society?
We should realize, CERN physicists just want to build and operate LHC collider despite of any risk, because it provides them safe and stable jobs and environment for scientific carrier. They're supported in their activities by lobby of private companies involved in technical support of LHC. We could say, high concentration of money in civilization leads to spontaneous formation of dense states of matter in simmilar way, like dense concentration of energy in universe. The desinformed rest of society underestimated these emergent relationships, which resulted into establishing of large groups of people, who are openly ignorant - if not even hostile - to further destiny of civilization.
